npm-load - Load config settings
npm.load() must be called before any other function call. Both parameters are optional, but the second is recommended.
The first parameter is an object hash of command-line config params, and the second parameter is a callback that will be called when npm is loaded and ready to serve.
The first parameter should follow a similar structure as the package.json config object.
For example, to emulate the --dev flag, pass an object that looks like this:
"dev": true }
For a list of all the available command-line configs, see npm help config
